AMABLE GRAVEL, OF PORTLAND, OREGON.

BUGKIN'G-WEDG-E.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed January 25, 1916. Serial No. 74,165

To all whom it may concern:

Be it known that I, AMABLE GRAVEL, a citizen of the Dominion of Canada, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Bucking- Wedges, of which the following is a specification, reference being had. to the accompanying drawings.

My invention relates to that class of devices used for opening the saw cut space in timbers and to split the same.

The object of my invention is to provide a device of the character mentioned which is a combination of a wedge for opening the saw cut space in timbers to allow the free operation of the saw and to hold the two parts in rigid position, also for splitting the timber. I attain these objects as well as other advantages, by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Figure 1 is a plan View of the device and shows wedge head in extension. Fig. 2 is a side view from the right side shown in Fig. 1. Fig. 3 is a sectional View on the lines 3-3 of Fig. 1. Fig. 4 is a view of the device applied in the saw cut space of a log, and showing cut of the smaller wedge fin in a separated portion. Fig. 5 is a view showing the application of the device in a log floating in water.

Like numerals refer to like parts in all views.

The wedge is cruciformed, the arm 6 composing one wedge and the arm 7 composing another wedge at right angle to the former.

A fin 8 extends longitudinally along one side of the arm 6 and a smaller fin 9 extends in like manner along the opposite side of the arm 6. The fin 8 has concave sides 88' for a suitable distance as shown in Fig. 8, and has a blade 8 at its free edge. The fin 9 has a blade 9 at its free edge. The wedge is provided with a ring 16 by which the wedge may be secured to a cord. A log 10 in Fig. 4 is shown upon the earth with the wedge arm 6 inserted in operative position. A severed portion 10 of the log 10 shows the cut 11 therein made by the fin 9. A saw 12 is shown in the log 10 below the wedge.

In Fig. 5 is shown a log 13 in the water secured to a raft by a dog 14 and the wedge in operative position above a saw 15.

It will now be seen that when a suificient cut is made the arm 6 is driven into the cut above a saw. The fin 8 being larger and having the concave sides 88, is very firmly secured in the larger part of the log and the smaller fin 9 is less firmly fastened 1n the part to be severed. It will be then observed that the two parts of the log are retamed in such a manner that the fins prevent the part to be severed from rolling and also prevent it from dropping away above the saw before the cut is completed. The insert or cut 11 of the fin 9 is shown in the log part 10 in Fig. 4. l/Vhen it is desired to saw a log in the water the same principle obtains to even a greater degree as the log will there roll or separate more easily than on land and in either case bind the saw or prevent a speedy, convenient and practical out. It is well known that much difficulty is experienced by woodsmen in sawing heavy logs in places often badly adapted to such work, and also where sawing is carried on in the water. Even with the log in the most adaptable place possible, the operation of sawing is difiicult. I contend that my device quite obviates these difiiculties. It will also be seen that the wedge arm 7 may be used as a splitt'mg wedge and may be conveniently inserted in the fin cut 11 for instance, or the cut left by the larger fin thus showing the usefulness of my very simple and economical device.

Having thus fully described my device, I claim- 1. A wedge of the character described having a fin 8 extending longitudinally thereof on one side, said fin being concaved in each of its sides and bladed at its free edge, a smaller fin on the opposite side of the wedge extending in like manner and bladed at its free edge, substantially as described.

2. A cruciform wedge of the character de scribed comprising a wedge arm 6 having a fin 8 extending longitudinally thereof on one side, said fin being concaved in each of its sides and bladed at its free edge, a smaller fin on the opposite side of the wedge extending in like manner and a transverse wedge arm 7 substantially as described.

AMABLE GRAVEL.
